Answer:
13 and 5
Step-by-step explanation:
x+y=18
x-y=8
_____
2x=26
x=13
So the first number must be 13
13+y=18
y=5
And the second number must be 5
Answer:
y = - 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 2 and c = 3, hence
y = - 2x + 3 ← equation in slope- intercept form
4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents
(8,6)...this means 8 lbs of potatoes cost $6
